A. Answer the following questions correctly. 1. Can a displacement from one point to another be zero, yet the distance involved in moving these points be non-zero? Can the distance between two points be zero, yet the displacement from one point to the other be non-zero? Explain. Can the velocity of an object be in different direction than the acceleration? Give example. Explain how a body moves with (a) uniform motion, and (b) uniformly accelerated motion. Is it possible for a body to accelerate when its velocity is constant? Explain. 4. 5. If an object has a greater speed, does it necessarily have a greater acceleration? Explain using examples. 2. 3.

A cat walks in a straight line, which we shall call the -axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat's motion and construct a graph of the feline's velocity as a function of time (Figure 1). I. Calculate the area under the graph between t = 0 and t = 6.0 s. (Express your answer to two significant figures and include the appropriate units.) II. For the time interval t = 0 to t = 6.0 s, what is the magnitude of the average velocity of the cat? (Express your answer to two significant figures and include the appropriate units.) III. Use constant-acceleration equations to calculate the distance the cat travels in this time interval. (Express your answer to two significant figures and include the appropriate units.)

Consider the following three displacement vectors: Vector A has a magnitude of 3.80 km and a direction that makes an angle of 36.0° south of west, vector B has a magnitude of 6.50 km and a direction that makes an angle of 15.0° north of west, vector C has a magnitude of 3.50 km and a direction that makes an angle of 37.0° north of east. Determine the magnitude of the vector X = B+C - A km 5. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 88.0 km/h; car (B) maintains a constant speed of 115 km/h. At t = 0, car (B) is 49.0 km behind car A. How far will car (A) travel from t = 0 before it is overtaken by car (B)? 1 6
